Shift in gears wont happen? Car stays in 4th.
Hello everyone, here is the thing, I have a 2007 mustang V6 automatic, has 140K miles
and all of a sudden when driving, it will just wont go into 5th gear, it will stay in 4th. I have
looked to see if it could be an overdrive problem, but I have no idea. Any input will be
greatly appreciated. Thank you.
